This invention relates to improvements in household appliances, and :more particularly to an applicator or holder which may be used to mount any one of a, selected number of work elements adapted to be used for treating "the surface of a work piece.

The primary object of the invention is "to provide a simple, inexpensive, sturdy appliance of this character which is readily grasped and to which a work element maybe applied quickly in a manner to be firmly held in desired position.

A further object is to provide a device of this character comprising a sheet metal member bent in generally cylindrical form to provide a hand grip portion and having diverging substantially coplaner flat portions projecting oppositely therefrom and terminating in fiangesbent in the direction of the handle and in converging relation with respect to the handle portion, whereby said flat portions provide bearing surfaces for applying pressure, and said flanges provide means adapted for locking engagement with a retainer and having a snap fit therewith.

.A further object is to provide a device of this character comprising a member having an integral hand grip and lateral portions projecting from the hand grip and terminating in flanges bent into converging relation and directed toward the hand grip, a retainer of generally U-s'hape adapted to have a snap fit upon the hand grip portion, and a pad unit having a tubularmember across sectional sides to fit'freely around and becarried by said retainer and locked or clamped between the margins of said U -shaped member and said handle'flanges.

A "further object is to provide a device of {this character adapted particularly for the application of fluid material to a working surface, comprising a hand grip portion, a retainer portion having a spring locked connection with looking elements projecting from the handle portion, and an applicator comprising a plurality of sheets of porous absorbent material bearing against said retainer and held and confined in place by a sheet of porous material of greater strength than said absorbent tissue and of a width to project around the retainer and be clamped between the margin of the retainer and the locking elements on the handle member.

Other objects will be apparent from the following specification.

In the drawings:

Fig. 1 is a front elevational view of the applicater.

1 Claim. (Cl. IS- 1233) Fig. 2 is an enlarged sectional side elevational view of the applicator illustrated by Fig. 1.

'Fig. 3 is a perspective view of the applicator shown in Fig. 1.

Referring to the drawings, the numeral 10 designates a body member and the numeral 1'2 designates'a retainer member. Both "of "these members ar'epreferably formed from sheet metal of suflicient thickness to retain their shapeand also possessing the property of at least'a limited amount of resilience. y Y

'The central portion of the member H3 is-bent transversely on a] curve of large radius at 14 to provide an elongated curved portion from which "portions l6 extend in inwardly converging relation. The curvature of the member It may be part cylindrical or part elliptical, and *thedimansions of the portions [4 and Hi are such that they provide an elongated hand grip portion which may be held comfortably in the hand. The portions ["6 merge at the bends is in spaced relation with laterally outwardly projecting fiat portions "23 "which lie substantially in the same plane or are disposed at a'slight angle with the outer ends of said 'flat portions 20 positioned downwardly and outwardly with respect to the bends l8 and {the inner margins of the portions 20. The plate forming the member I!) terminates at :its opposite longitudinal margins in flanges 22 which are bent :upwardly and inwardly in converging relation, terminating spaced from the portions I6 of the handle. If desired, the part I10 may carry a tubular socket i24 centrally of its length and inclined relative to the central plane of the member ID. The socket 24 'isfixed'ly secured :to the member It. at the bent portion I 4 :thereof and communicates with an opening inthe portionfll. n v Y v The retainer 12 preferably comprises a plate 26 of substantially the same length as the member I l] which is bent transversely in concavoconvex form on an arc of large radius. The width of the plate 26 is greater than the width of the member In measured at the junction between the parts 20 and 22 of the member Ill. The plate 26 is bent at 28, and flanges 30 form the margins of said plate, said flanges being arranged in converging relation with their free inner ends spaced apart a distance substantially equal to the spacing of the tips of the flanges 22 on the handle portion In. If desired, the flanges 30 may be formed of a double thickness of the material by providing a return bend of the material, thereby reinforcing and strengthening said flanges.

The arrangement of these parts is such that the retainer 12 may be applied to the body portion l either by longitudinal sliding of the parts or by a snap fit. It will be observed in this connection that the formation of the body member In with its spaced converging portions it provides resilience of the body I!) and permits the side portions l'6 thereof to be sprung inwardly to permit the leading or free edges of the flanges 30 to snap thereover when the parts are applied together in a direction perpendicular to the face of the retainer [2. The advantages. of the snapon type of application will be referred to hereinafter. It will be apparent also that the curved plate 26 of the retainer constitutes a spring member and that the curvature of this member may,

be such that it exerts an inward spring pressure acting against the outward spring pressure of the body l0 when the parts are assembled, thereby insuring a snug tight interlock of the parts when assembled. It will further be observed that the parts are so proportioned that when the outer faces of the flanges 22 of the body ID fit between the flanges 30 and bear against the inner faces thereof, the bent portion 2| of the body between the body parts 28 and 22 will be urged into engagement with the plate 28 in inwardly spaced relation to the bends 28 of the retainer [2. Thus four points of continuous longitudinal engagement are provided between the body ill and the retainer l2, two such longitudinal lines of engagement being between the flanges 22 and 30, and the other two lines of longitudinal engagement being between the bends 2| and the opposite sides of the plate 26. This serves to solidly connect the parts together, to prevent loose play therebetween, and to provide for multiple con tinuous lines of engagement at which the pressure applied to the handle or body part is transmitted to the retainer part (2. r

A pad 32 formed of felted wool or of any other manner of desired absorbent properties and capable of retaining its shape and form is utilized. This pad 32 is secured to a tube 34 formed of cloth, paper or any other suitable flexible sheet material. These pads may be secured together by the use of glue, or by staples, stitching or other suitable means. tube is large enough to permit it to fit freely around the retainer 12, and to permit the flanges of the retainer to receive and interlock with the flanges 22 of the body ill. The assembly of the parts It and 12 serves to draw the tube 34 taut into firm non-slipping engagement with the interlocked parts ID, [2, it being understood that the cross-sectional size of the tube is carefully. selected to insure that the tube is so drawn taut The cross-sectional size of the ance adapted for many different household uses,

each characterized by convenience, simplicity, and avoidance of contact of the user with the working element. The device may be sold as a part of a set including the parts 10 and I2 and such other supplementary or auxiliary parts to be used therewith as the user may desire.

While the preferred embodiment of the invention has been illustrated and described herein, it will be understood that changes may be made in the construction within the scope of the appended claim without departing from the spirit of the invention.

I claim:

A device of the character described comprising a body of resilient sheet metal having a longitudinal central handle portion and diverging side portions,.a handle projection from said central handle portion, and a channel-shaped retainer having inwardly converging sides adapted to receive and grip the side portions of said body therebetween, and a pad unit adapted to bear against the outer surface of said retainer and including a pad member and a flexible tubular member secured to said pad member, said tubular member being of a cross-sectional size to fit freely around said retainer and to be drawn taut upon insertion of the side portions of said body within said retainer in interlocked relation thereto.
